Design, synthesis and antimalarial activity of a glyoxylylhydrazone library
摘要:
Synthesis of a new family of quinolylhydrazone derivatives and evaluation of their activity against a chloroquine-resistant strain of Plasmodium falciparum are described. The best compound displayed an activity 6-fold higher than chloroquine. None of the active compounds were found to inhibit beta-hematin formation in vitro in the same range as chloroquine and five among them displayed lower calculated vacuolar accumulation ratios, suggesting the implication of a different mechanism of action.

For the treatment of malaria which affects nearly 200 million people each year and the continued exacerbation by the emergence of drug resistance to most of the available antimalarials, the "covalent bitherapy" suggests hybrid molecules to be the next-generation antimalarial drugs. In this investigation, new hybrids of 4-aminoquinoline and pyrimidine moieties that show antiplasmodial activity in the nM range against chloroquine-resistant as well as chloroquine-sensitive strains of Plasmodium falciparum have been prepared. Cytotoxicity evaluation and mode of action of most potent hybrid molecule have been conducted.

Similar Structure−Activity Relationships of Quinoline Derivatives for Antiprion and Antimalarial Effects
Prion diseases are invariably fatal neurodegenerative diseases, in which the infectious agent consists of PrPSc, a pathogenic misfolded isoform of the normal cellular prion protein ( PrPC). Until now, no pharmacological options exist for these novel pathogens. Here we describe the screening of a series of polyquinolines and quinolines linked to a large variety of terminal groups for their ability to cure a persistently prion infected cell line (ScN2a). Several compounds showed antiprion activity in the nanomolar range. The most active molecule, named 42, had a half-effective concentration (EC50) for antiprion activity of 50 nM. In a library of quinoline derivatives we were able to identify several structure-activity relationships (SAR). Remarkably, antiprion SAR in ScN2a cells were similar to antimalarial SAR in a cell model of malaria, particularly for the sulfonamide quinoline derivatives, suggesting that some molecular targets of antiprion and antimalarial substances overlap.
